Roma Holocaust Memorial Day is observed in several European countries, including Poland, Croatia, the Czech Republic, Lithuania, Slovakia, and Ukraine, every August 2. Established in 1996 by leaders of Roma organizations from ten European countries and the United States, this solemn day honors the memory of the Roma and Sinti victims of the Nazi regime. During World War II, the Romani people, classified by the Nazis as “enemies of the race-based state,” faced genocide, with estimates of 200,000 to 500,000 killed. A significant number, approximately 23,000 Roma and Sinti, perished in the Auschwitz concentration camp, where many were subjected to forced labor and medical experiments. The day commemorates the liquidation of the Gypsy camp at Auschwitz on August 2, 1944, marking a tragic chapter in history. The observance is recognized by the European Parliament and the Council of Europe, and in Poland, it was officially declared as Genocide Remembrance Day of the Roma and Sinti in 2011.
